Manufacturers of premium quality AR15 rifles, 2A Armament debuted two ultralight rimfire setups that can be used as training kits or as standalone rifle platforms for hunting, target shooting or general plinking. The kits come in two forms: a drop in bolt carrier group that works with your existing .223 barrel or a barrel and bolt combination for building a complete upper.

As with all 2A Armament products, the rimfire kits are well made and come complete with everything you need to get your rifle up and running. Of course, they also had a full display of their centerfire rifles, some of them coated in optional camouflage patterns and others chambered in 6.5 Creedmoor.

2A Armament has additional plans for new products that could be available later this year. Details and specifications can be found below .
